> Project: Flink
> Issue Type: Bug
> Components: Connectors / Common
> Affects Versions: 1.12.0, 1.11.3
> Reporter: Jiangjie Qin
> Assignee: Jiangjie Qin
> Priority: Blocker
> Labels: pull-request-available
> Fix For: 1.11.3, 1.13.0, 1.12.1

>
> The {{SourceOperatorStreamTask}} does not implement {{cancelTask}} and
> {{finishTask}} at this point. This causes resource leak on job cancellation
> of finish.
> Currently there are three cases that a Job may exit.
> # Canceled - {{cancelTask()}} method will be called to close the
> SourceOperator.
> # Stopped with a savepoint - {{finishTask()}} method will be called to close
> the SourceOperator.
> # Runs to the EndOfInput - the SourceOperator is closed in
> {{StreamTask.afterInvoke()}}.
